Inraovnucnr In summe-BUCKET PROPELLBRS.

TO ALL WHOM IT MAY GONCERN l Be it known that I, JACOB Bussen, of the city of Philadelphia, and State of Pennsylvania, have invented certain'new and useful Improvements in theManner ol' Arranging Shifting-Bucket Propellers oncanal and other boats; and I do hereby declare the following to be a full, clear, and exact description' of the same, reference being had to the accompanyingr drawings, making a part of this speciication, in which'- 'Figure 1 represents a side view ofa boat with the propeller connected thereto or therewith.

li'ignre 2 represents a view of the bottom of the boat, having a portion thereof removed to show a means of giving motion to the propellers, and also showing the arrangement o'f the propellers on the bottom of or underneath the boat. y Y

Figure 3 represents a view of the propellers as arranged underneaththe boat, and showing, as is also shown in. fig, 2, the moving parts in two dilerent positions, by black and by red lines.

Similar letters of reference, where they occur in theseparate figures, denote like parts in all of the-drawings.

Letters Patent of the United States were granted to -me `on 'thc second day of July, 1867, for an improvement in shifting-bucket propellcis, substantially such as shown in the accompanying drawings, but arranged as side propellers.

The ohjectof my present invention is to arrange this style oi propeller on the bottom of or underneath the boat, so as to apply it to the propulsion of canal or other similar boats.

To enable others skilled in the art to make and use my invention, I will proceed to dcscribethe same with reference to the drawings. v

On thebottom of the boat A. are arranged guards B B, which form ways or guides, in which thetwo frames,

'C D, one at or near each end of the boat, maybe moved by gear, E, working in the -racks F connected,`

respectively, with the 'frames 'C D, or by any other well-known mechanism driven bypower that will reciprocate said frames.

I In each of the sliding or reciprocating frames are hung, respectively, the floats or buckets I 2 and 3 4, so that when not otherwise controlled, they will drop into a vertical, or nearly so, position, and be suspended on their journals; and attached to each frame, so as to more with them, 'are supports a a, that brace the buckets or floats when propelling, but allow them to iloat upxand outot' actio'n'when returning for the next propellingaction. There is also upon each frame a tripper, I), hung theretoby screws c @passing through the -slots d, by which one set ofbuckets may be vthrown out of and the other set into action at pleasure, for changing'the moving direction of the boat either forward or backward, or, as 'it may be termed, .either ond foremost, -which is accomplished by a shiftingdever, e, which works the shifting-hanf, and which-bar, by means ofits notches or s'houldersg, and the projections L on the tripper, moves the latterfand throwsy the set of floats that were previously in action 'up out of action, and allows the other set to drop down intoa propelling position. The v iicats 1 in iig. 2, and 4 in iig. 3, are represented as in their propelling position, and the others as inactive, whilst by thc red lines in thesame figures the floats 3 2 are propelling, and the othcrspassive or inactive.

The frames C D, which carry the floats or buckets, may be connected to-their respective racks, F Gr, by rods HH, and they approach 4and recede from each other by simultaneous movements, but onefbucket in 'each always propelling, orV rather the' boat is constantly propelled, first by .the bucket in one frame, and then by a. bucket in the other frame, andwhen its motion is to hc reiersedj the lever e is shifted, which brings into action another pair of buckets, which alternately propel the boat, the pair just thrown out of'action not in anywise interfering with. them.

This simultaneous approaching and receding, or to-and-fro motion of the frames and buckets, may be procured in many ways, and I do not confine my invention to any special device for operating them, solong as they are reciprocated in pairs,.or by mates or fellows, as herein shown. l

Having thus fully described my invention, what I claim therein asincw, and desire to secure by Letters Patent, is t The arrangement of the frames carrying the shifting-buckets upon the bottom of or underneath the boat, so that both series of buckets shall work in the same plane, and guarded, guided, and shifted for changing the direction of the boat by devices substantially such as set forth and described. v
